The crew of the Plastiki used satellite data gear from Inmarsat and HP laptops and phones to broadcast classroom sessions and news interviews from the middle of the ocean. Over 16,000 people followed the voyage of Plastiki through Twitter and Facebook alone.

No land in sight for miles, but the crew stayed updated with every kilometre it covered. One of the crew members even stayed in touch with his wife via Skype as she gave birth.

The operations centre of the Plastiki keeps the boat going. The Plastiki is powered by several car batteries. The crew had to make modifications to the power supply to make sure it could go the distance.

Skipper Jo Royle tells us that the walls inside the armadillo are made from PET bottles with a foam core, meaning that the boat was able to bend and stretch on the voyage.

The catamaran-shaped Plastiki is kept afloat by hundreds of PET bottles lined within the boat's arms, or amas.

A fresh recruit onto the tech journalism battlefield, Luke Hopewell is eager to see some action. After a tour of duty in the belly of the Telstra beast, he is keen to report big stories on the enterprise beat. Drawing on past experience in radio, print and magazine, he plans to ask all the tough questions you want answered.
